| Income Taxes                         | INCOME TAXESAs of October 1, 2016, the Company had $250 million accrued for uncertain tax positions, all of which would affect the Company’s effective tax rate if recognized. Additionally, the Company had $38 million accrued for gross interest and penalties as of October 1, 2016. At January 2, 2016, the liability for uncertain tax positions was $338 million and the accrual for gross interest and penalties was $58 million. The Company is subject to U.S. federal income tax as well as income tax of multiple state and foreign jurisdictions. The Company has substantially concluded all material U.S. federal, state, foreign and local income tax matters for all tax years through 2004. During the third quarter of 2016, the Company entered into a settlement agreement with the Internal Revenue Service (IRS), closing its 2008 to 2011 tax examinations. The settlement resulted in a $157 million reduction of the Company’s uncertain tax positions during the third quarter of 2016 and reduced its accrual for gross interest by $25 million. The settlement did not result in a material adjustment to tax expense in the third quarter of 2016. The majority of cash owed to the IRS associated with the settlement was paid during the first nine months of 2016 with the remaining amounts expected to be paid to the IRS in the fourth quarter of 2016.The Company's effective income tax rate was 13.5% and 17.6% for the third quarter of 2016 and 2015, respectively, and 16.3% and 12.7% for the nine months ended 2016 and 2015, respectively. The Company’s effective income tax rate differs from the U.S. federal statutory rate each year due to certain operations that are subject to tax incentives, state and local taxes and foreign taxes that are different than the U.S. federal statutory rate. In addition, the effective tax rate can be impacted each period by discrete income tax factors and events. During the three months ended October 1, 2016, special charges, acquisition-related costs and discrete income tax items unfavorably impacted the effective income tax rate by 0.1 percentage points. During the nine months ended October 1, 2016, special charges, acquisition-related costs, other-than-temporary impairments and discrete income tax items unfavorably impacted the effective income tax rate by 3.1 percentage points. Special charges, acquisition-related costs and discrete income tax items recognized during the third quarter of 2015 unfavorably impacted the effective rate by 1.6 percentage points and favorably impacted the effective rate by 4.2 percentage points during the first nine months of 2015.During the first nine months of 2016, the European Commission concluded that decisions by the tax authorities in Belgium regarding corporate income taxes paid under certain excess profit rulings, including the ruling previously granted to one of the Company’s subsidiaries, did not comply with European Union rules on state aid. Based on the applicability of this conclusion to the Company's 2009 through 2014 tax returns in Belgium, the Company recorded a liability of 43 million Euros ($48 million as of October 1, 2016) including interest to reserve for this uncertain tax position during the first nine months of 2016. |
